Due to a small debate on this term, I've been giving it some thought.
The proper definition of a shell "bouncing" should be doing 0 damage on both SD and DP, but that is rarely the case.
Usually, when a ship is AWed, it reduces the damage of incoming shells significantly, for example, a AWed QV will sometimes take 100 damage per shell (instead of 0) from a Kaiser at 40 degrees whe it's AWed.
This damage dealt is quite insigniciant to the DP of the QV (41000 or so), but it isn't a true "bounce" of said shells.
My question is,
What would be the proper definition of a shell "bouncing"? And if there is none, could one be made with a defined percentage of damage reduced by the AWed ship?
For example, if an AWed ship reduces the damage of a shell hitting it by over 80% of it's potencial damage, it is concidered a partical bounce, while over 90% is concidered a full bounce.
